Answer:
The correct answer is - option b. to generate a protein with a run of consecutive glutamines.
Explanation:
The initiation code AUG is the code for methionine and as well as the initiation code for the particular protein or peptide chain. In this protein, there is a repeat of CAG is increased with the initiation code so, even though they are in zero reading frame they code for their amino acid which is glutamine.
So. an increased number of CAG repeats will result in a protein with the a run of consecutive glutamines.
Answer:
All these are emerging infectious diseases.
Explanation:
The emerging infectious diseases refer to the infections, which have appeared freshly within a population or those whose occurrence or geographic range is enhancing briskly or is threatening to upsurge in the coming time. The emerging infections can be a result of:
1. Known agents, which have dispersed to novel geographic locations or new populations.
2. Previously unknown or undetermined infectious agents.
3. Previously known agents whose function in particular diseases was not determined previously.
According to WHO, infectious diseases are emerging at a rate, which has not been noticed before. Since the 1970s, many infectious diseases have been discovered like Ebola, SARS, avian influenza, mad cow disease, and West Nile encephalitis.
With the individuals traveling much more to far greater distances in comparison to the past, encountering with wild animals, and living in more densely populated regions has caused the emerging infectious diseases to spread briskly and is resulting in global epidemics, which is a major worry.
Answer:
0.8
Explanation:
There is a population where the frequencies of allele 1 and allele 2 are 0.7 and 0.3, respectively
Let's use GG to represent allele 1
Let's use gg to represent allele 2
So we can equally say that;
GG = p = 0.7
gg = q = 0.3 ( from Hardy-Weinberg Equilibrium)
So, given that the selection coefficient = 0.2
We known that the cross between GG and gg will definitely results to (GG,Gg and gg)
Then the fitness of these genes can be represented as:
1 - s, 1 and 1 - t respectively.
Thus. the allele 1's genotype fitness can be determined as
= 1 - s ( where s is the selection coefficient)
= 1 - 0.2
= 0.8
Answer:
Below an active volcano lies magma chamber. Magma is the liquid which makes the lava. It’s located within the crust of the earth.
Explanation:
Magma chambers lies within the crust of the earth. Volcano is made up of magma which has come in contact with water. Upon contact with water, it erupts.
Once the volcano erupts it can destroy all forms of life surrounding it. The parts where the lava has fallen are no more capable of inhibiting.
